support.
;
Use the device in accordance with its degree of protection.
Information on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may change during the production period.
This has no effect on strength, dimensional stability and dimensional
accuracy.
The color pigments in the paints used perceptibly react to UV light over
the course of time. The product is to be protected against UV radiation to
prevent the formation of patches and fading. Changes in color are not a
reason for complaint and are not covered by the warranty. UV radiation
in the frequency range and the intensity of natural solar radiation has no
effect on the technical properties of the products.
3.4 Mounting data
Further mounting data can be taken from the product drawing or Chapter
4.1 Mechanical connection as required.

For screw clearance, see Chapter 3.1 Product drawing
;
Secure the screws against unintentional loosening (e.g. use self-
locking screws).
